Hi EveryOne,
I have some question about VIP_trimmer on DM385 （I·m using IPND_RDK3.5）.
VIP trimmer setting code in captureLink is as follows:
...
pVipCreateArgs->videoCaptureMode =
VPS_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_DISCRETE_SYNC_HSYNC_VSYNC;
...
...
vipCropPrms.channelNum = 0;
/* Enable VIP trimmer in discrete sync mode */
if((pVipCreateArgs->videoCaptureMode ==VPS_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_DISCRETE_SYNC_ACTVID_VBLK) ||
(pVipCreateArgs->videoCaptureMode ==VPS_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_DISCRETE_SYNC_ACTVID_VSYNC)||
(pVipCreateArgs->videoCaptureMode ==VPS_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_DISCRETE_SYNC_HSYNC_VSYNC))
{
vipCropPrms.vipCropEnable = TRUE;
}
else
{
vipCropPrms.vipCropEnable = FALSE;
}
vipCropPrms.vipCropCfg.cropStartX = 236;
vipCropPrms.vipCropCfg.cropStartY = 41;
vipCropPrms.vipCropCfg.cropWidth = 1920;
vipCropPrms.vipCropCfg.cropHeight = 1080;
status = FVID2_control(pInst->captureVipHandle,
IOCTL_VPS_CAPT_SET_VIP_CROP_CFG,
&vipCropPrms, NULL);
UTILS_assert(status == FVID2_SOK);
...
The input video format is 1080P30(clk = 74.25MHz,HSync = 33KHz,VSync = 30Hz),But with the above paremater ,captureLink can not get the right data in buffer,in only capture 15 frames per second.
If I don`t use trimmer to crop blanking region,captureLink can get 30 frames per second in buffer,with blanking region and active date.
I found that when cropStartX + cropWidth > 2048,VIP paser cannot work well.why ? anywhere have limit on this ? How can I crop 1080P active data correctly ?Thanks
